SUBMERGED DIKE.

SPECIFICATION forming part of Letters Patent No. '761,898,'dated'June 7. 1904.

Application filed January 21, 1901. Serial No. 44,148. (No model.)

To on whom it may concern.-

Be it known that I, DAVID NEALE, residing at Fort Calhoun, in the county of Washington submerged dikes, and embodies a cell of per-,

meable material adapted to form after having been placed below the water-surface a mud-1 chamber.

The object of my invention is to provide a light, portable, and permeable cell forming a.

unit, a plurality of these cells. being used to form a fascine which is lowered below the surface of the water and in course of time becomes mud and sand filled and so offers a solid obstruction to the water-currents to deflect thesame. I These cells when used in series may be made to form-a mat or fascine or be submerged in a series or be sunk singly.

In the accompanying drawings I have shown in Figure 1 a perspective view of one of these cells. Fig. 2 shows a View of a. simplefastening device, while Fig; 3 shows one of the connecting-rods.

As set forth, the aim of my invention is to provide a cell comprising a housing made up of permeable-material and which is closed at both ends.

In the accompanying drawings I have shown a housing made up of a series of longitudinal which being shown in the drawings. sills 2 2 are united by a plurality of transverse pieces 3 3. while the remaining sills 2 are united by means of the transverse frame-pieces 5 5.- These frame-pieces form, as it were, the top and bottom of a cell, and the framework is made by uniting the transverse pieces 3 to the transverse pieces 5 by means of the bars a a, which pass through suitable openings within these pieces and are nailed or otherwise secured within the transverse pieces.

Spanning the frame-section comprising the transverse pieces 5 and the sills 2 is a covering made up .of brush, cornstalks, or any other suitablematerial, so that a permeable wall is formed, as is shown at a.

The sides are made up in providing a permeable mass between the bars a and the bars 5, the bars 6 extending through the sills 2 2 and through the transverse pieces3 and 5, and

between these bars a and Z) the material is held, as will'be understood in referring to Fig. 1.

The brush is made to extend a considerable 7 distance beyond the skeleton framework and is closed at each end by means of a wire a or by other suitable means, as is shown, so that I provide a cell closed at both ends and made of permeable material. To further strengthen the structure, I bind the same with one or more encircling strands of wire, as is shown at a z in Fig. 1.

For the sake of rigidity the bars 6, one of which is shown in detail in Fig. 4, may be provided with the lugs c, which work into a suitable slot 6 within the transverse pieces 3 and 5, so that the skeleton frame is rigidly held. These frames, however, may be constructed in any suitable manner, the object of my invention being to provide a permeable cell closed at both ends, and I do not wish to confine myself to any particular shape or limit myself to any particular structure, and,

Having thus described my said invention, what I claim as new, and desire to secure by 1 Letters Patent, issills 2 2 and two counterpart sills 2, one of These low chamber and having opposite ends pointed to form an entirely-closed chamber.

A cell of permeable substance having a hol- DAVID N EALE.
